I think it is now clear–the real cause of global warming is global cooling. For example from the 1940s through the 1970s the earth was cooling. This caused people to have to burn lots of carbon fuels to heat their homes which put more CO2 in the atmosphere. This gave us the global warming we had from the 1970s to late 1990s. Now the earth appears to be cooling again which is clearly causing us all to burn more fuel to heat our homes. I know my furnace is cranking. The cycle starts again. If it wasn’t for all these periods of global cooling we wouldn’t have global warming.
